Under Seat Storage for 2019-2025 Chevy Silverado & GMC Sierra - Rear

In this review the MAXDOM under seat storage for Chevy Silverado and GMC Sierra is evaluated for owners who need more organized rear storage without permanent modification. The bottom line: this underseat organizer is designed for Double Cab and Crew Cab rear seats from 2019 through 2025 and its single biggest advantage is turning wasted underseat space into tidy, large-capacity compartments that look close to factory-installed. Installation requires some assembly and occasional trimming of the factory floor mat, but the result is a durable, matte ABS storage solution that improves everyday utility.

Key Features

• Exact vehicle fit: Built to fit 2019-2025 Chevy Silverado and GMC Sierra 1500 and 2020-2025 2500/3500 HD double and crew cabs so owners get a tailored underseat organizer.
• Three-module set: The package contains 3PCS modules plus 2PCS dividers and screws, providing multiple compartments to separate tools, gear, and personal items.
• Premium material: Molded from ABS plastic with a matte surface for a robust, low-gloss finish that resists scratches and looks integrated with interior trim.
• Large capacity: Designed to make reasonable use of underseat space so larger items and frequently used tools can be stored out of sight yet remain accessible.
• Assembly required: Modules are shipped disassembled and need straightforward assembly with included fasteners, allowing compact shipping and secure installation.
• Minor floor mat adjustment: Some installs require trimming the factory floor mat for a flush fit, enabling a neat, stable installation.

Who It's For

This organizer is a practical choice for Silverado and Sierra owners who regularly carry tools, recovery gear, work equipment, or everyday items and want them stowed under the rear seat without bulky aftermarket drawers. It is especially useful for people who appreciate a near-factory look and sturdy ABS construction.

It is less appropriate for owners of single cab or long-bed models, or anyone unwilling to perform light assembly or trim a floor mat. If you need a lockable or heavy-duty metal drawer system rather than plastic compartments, look at dedicated heavy-duty underseat drawers instead.
